A brief discussion on the test method of concrete impermeability
According to the measurement of the medium flowing through the sample, the pressure inside the container is changed, the pressure difference between the two ends of the sample is maintained, and the amount of the medium flowing through the predetermined time is measured to determine the impermeability of the concrete test piece.
